The relationship between mind and necessity is one of the major points of difficulty for the interpretation of Plato’s Timaeus. At times Timaeus seems to say the demiurge is omnipotent in his creation, and at other times seems to say he is limited by pre-existing matter. Most interpretations take one of the two sides, but this paper proposes a novel approach to interpreting this issue which resolves the difficulty. This paper suggests that in his speech Timaeus presents two hypothetical models (...) of creation, one with an omnipotent demiurge and one where he is limited by matter, so as to investigate their theoretical and empirical validity. Further, he shows that each model is ultimately an inadequate explanation of the first principles of the cosmos. Timaeus’ speech is therefore properly understood to be aporetic: it leaves its listeners aware of the difficulties inherent in the two models of creation, but without a more viable alternative.

I argue that Plato thinks that a sunaition is a mere tool used by a soul (or by the cosmic nous) to promote an intended outcome. In the first section, I develop the connection between sunaitia and Plato’s teleology. In the second section, I argue that sunaitia belong to Plato’s theory of the soul as a self-mover: specifically, they are those things that are set in motion by the soul in the service of some goal. I also argue against several (...) popular and long-standing interpretations, namely, that sunaitia correspond to Aristotle’s idea of hypothetical necessity, that sunaitia are the ‘how’ in an explanation (whereas the true cause is the ‘why’), and that Plato’s causal views should be read through Aristotle’s fourfold schema. I conclude the article by surveying the history of sunaitia after Plato’s usage. (shrink)

Aristotle claims that the virtuous person acts for the sake of to kalon. To understand this idea, I examine the analogy he draws between craft and virtue. I argue that the kalon is a formal feature of well-ordered wholeness and that the virtuous person takes intellectual pleasure in perceiving (or remembering or imagining) the kalon-in-action, akin to pleasure in observing artworks or works of nature. However, the virtuous person’s pleasure in kalon action is primarily a pleasure of practical reason. In (...) these ways, Aristotle’s concept of the kalon is and is not like the modern aesthetic concept of the beautiful. (shrink)

Many assume that Plato's Form of the Good is a final cause. This might be true if one assumes an Aristotelian definition of final cause; however, I argue that if one adopts Plato's conception of final causation as evidenced in the Phaedo and Timaeus, the claim that the Form of the Good is a final cause for Plato is untenable.

In Plato’s Gorgias 482c4–484c3, Callicles advances a concept of natural justice: the laws of the polis must agree with nature, that is, human nature. Since human nature is characterised by its desire to get a greater share, nature itself makes it legitimate that stronger human beings get a greater share than weaker ones. Socrates objects: Callicles’ theoretical approach to civic life poses a threat to the polis’ community, its citizens, and to the friendship amongst its citizens. However, Socrates accepts Callicles’ (...) premise, that the laws of the polis must agree with nature. Still, he disagrees with Callicles about the nature of human nature and proposes an alternative theory of human nature, eventually leading to his alternative concept of natural justice. The article explains the arguments underpinning these two concepts of natural justice, including the conflicting understandings of human nature. (shrink)

It is a notion commonly acknowledged that in his work Timaeus the Athenian philosopher Plato (_c_. 429–347 BC) laid down an early chemical theory of the creation, structure and phenomena of the universe. There is much truth in this acknowledgement because Plato’s “chemistry” gives a description of the material world in mathematical terms, an approach that marks an outstanding advancement over cosmologic doctrines put forward by his predecessors, and which was very influential on western culture for many centuries. In the (...) present article, I discuss inter-transformations among Plato’s four types (fire, air, water, and earth) as well as the interpretation they received in the literature. I find that scientists and scholars generally emphasized (and often misunderstood) mathematical aspects of these “reactions” over the philosophical ones. I argue that Plato’s “chemistry” in fact bears on crucial topics of his philosophical system, such as Forms, Becoming, causation and teleology. I propose that consideration of these doctrines help to understand not only the sense of his “chemical” reactions, but also the reason why their stoichiometry is by surface balance and is restricted only to types that come to be and pass away but not to those that provoke the inter-transformations.

. The aim of this paper is to analyse the ways in which the nature of true philosophers is described in Plato’s Timaeus. By examining the distinction between two kinds of opinion – one absolutely false, the other reliably true – I will try to show that Plato coined a new term to denote both true philosophers and the characteristics of their knowledge. From being a ‘love of wisdom’, true philosophy came to be defined as a ‘passion for science’. Finally, (...) I will try to illustrate the protreptic intent underlying this choice of words and how it concerns the main critical target of the Timaeus, the so-called Presocratics. (shrink)
